DESCRIPTION
Thi s “stan dard rec overy” rectifier diode series is m ilitary q uali fi ed and i s ideal for high-reliability
applications wher e a fail ure cannot be t olerated. Th ese industr y-recogn ized 5.0 Amp rated
rec tifiers for wo r king peak r everse volt ages from 200 to 1000 volts are hermet ically sealed
with voidless-gl ass constr uction u sing an internal “ Category 1” metallurgical bond. T hese
devic es a r e al so available in surfac e mount MELF package configu r ations. Mic r osemi als o
of fers numerous oth er r ecti fi er product s to m eet higher an d lower curr ent r atings with various
rec ove r y t im e sp eed requ iremen ts in cluding fast and ult r afast device types in both th r ough-
hole and sur face m ount packag es.

MAXIMUM RAT INGS
Notes: 1. At .375 in ch ( 9.52 mm) lead length from body.
2. De rate li ne ar ly at 22.2 mA/ºC from +55 ºC to +100 oC.
3. These IO ratings are for a thermally (PC boards or other) mounting methods where the lead or end-cap temperatures cannot be maintained
and where thermal resistance from mounting point to am bient is still sufficiently contr olled where TJ(MAX) do es not exce ed 175 oC. This
equates to RθJX ≤ 47 ºC/W.
4. De rate li ne ar ly at 26.7 mA/°C above TA= +100 °C to +175 ° C am bi e nt .
• CASE: Hermetically sealed voidless hard glass with Tungsten slugs.
• TERMINALS: Axial-leads are Tin/Lead (Sn/Pb) over Copper. R oHS compliant matte-Tin is available for commerci al only.
• MARKING: Body paint and part number, etc.
• POLARITY: Cathode band.

SYMBOL S & DEFI NITIONS
Symbol
Definition
VBR
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
VRWM
Working Peak Reverse Voltage: The maxim um peak voltage that can be applied over the operating tem perature range
excluding all transient voltages (ref JESD282-B).
IO
Average Rectified Output Current: The Output Current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave
input and a 180 degree conduction angle.
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
IR
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
trr
Reverse Recovery Tim e: The time interval between the instant the current passes through zero when changing from
the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs.

1. Dimensions are in inches.
2. Millimeter equivalents are given for general information only.
3. The BL dimension shall include the entire body including slugs and s ections of the lead over which the diameter
is uncontrolled. This uncontrolled area is defined as the zone between the edge of the di ode body and extending
.050 inch (1.27 mm) onto the leads.
4. Dimension BD shall be measured at the largest diameter.
5. In accordance with ASME Y14.5M, diameters are equivalent to Φx symbology.
